Contact lenses loaded with vitamin E may treat glaucoma Posted: 29 Mar 2010 08:00 AM PDT The popular dietary supplement vitamin E, loaded into special medicated contact lenses, can keep glaucoma medicine near the eye -- where it can treat that common disease -- almost 100 times longer than possible with current commercial lenses, scientists report.

Making car fuel from thin air Posted: 29 Mar 2010 08:00 AM PDT Researchers in the UK are working on a project that could take carbon dioxide from the air and turn it into car fuel. The project aims to develop porous materials that can absorb the gas that causes global warming and convert it into chemicals that can be used to make car fuel or plastics in a process powered by renewable solar energy.

High systolic BP in patients with chest pain linked with favorable prognosis Posted: 29 Mar 2010 08:00 AM PDT New research finds that there is an inverse association between the level of supine (lying face up) systolic blood pressure measured on admission to an intensive care unit for acute chest pain and risk of death at one year, with those patients having high systolic blood pressure having a better prognosis after a year.

Naval research laboratory takes a close look at unique diamonds Posted: 29 Mar 2010 08:00 AM PDT Naval Research Laboratory, which has been involved in pioneering work involving chemical vapor deposition of diamond and the use of diamond materials in advanced technologies relevant to the Department of Defense since 1987, has recently undertaken some new projects in diamond research. In collaboration with the Smithsonian Institution Museum of Natural History, NRL researchers have begun studying unique and historic natural colored diamonds to understand and characterize the defects/impurities, which cause the color.

Transition into adult health care is a rocky road for 20 somethings Posted: 29 Mar 2010 08:00 AM PDT Young adults, a generally healthy population, are increasingly flocking to emergency departments instead of outpatient clinics for medical treatment.

Compulsive eating shares addictive biochemical mechanism with cocaine, heroin abuse, study shows Posted: 29 Mar 2010 05:00 AM PDT In a newly published study, scientists have shown for the first time that the same molecular mechanisms that drive people into drug addiction are behind the compulsion to overeat, pushing people into obesity.

Coronary artery development mystery solved, may lead to better bypasses Posted: 29 Mar 2010 05:00 AM PDT Scientists studying cardiac development in mouse embryos have identified the source of cells that become the coronary arteries -- the vessels that deliver blood to nourish the continuously pumping heart muscle.

Vast microbial diversity of carnivorous pitcher plant uncovered Posted: 29 Mar 2010 05:00 AM PDT The microbial ecosystem inside the carnivorous pitcher plant is vastly more diverse than previously thought, according to new research.

Slowing down immune system's 'brakes' may improve HIV vaccines Posted: 29 Mar 2010 05:00 AM PDT Like a skittish driver slamming the brakes, a special class of T cells may be limiting the effectiveness of therapeutic vaccines for HIV by slowing the immune system response too soon, report health science researchers. Their study may help researchers improve the efficacy of such vaccines by devising methods to circumvent the braking mechanism of these cells.

A two-in-one test for detecting E. coli in ground beef and other foods Posted: 29 Mar 2010 05:00 AM PDT Scientists have developed the first two-in-one test that can simultaneously detect both the E. coli bacteria responsible for terrible food poisoning outbreaks, and the toxins, or poisons, that the bacteria use to cause nausea, vomiting, diarrhea and other symptoms in its victims.

Mother-son relationship key to emotional development Posted: 29 Mar 2010 05:00 AM PDT New research shows that children, especially boys, who have insecure attachments to their mothers in the early years have more behavioral problems later in childhood.

Single gene dramatically boosts yield, sweetness in tomato hybrids Posted: 29 Mar 2010 02:00 AM PDT Giving tomato breeders and ketchup fans something to cheer about, scientists have identified a gene that pushes hybrid tomato plants to spectacularly increase yield. The yield-boosting power of this gene, which controls when plants make flowers, works in different varieties of tomato, and crucially, across a range of environmental conditions.

Paired drugs kill precancerous colon polyps, spare normal tissue Posted: 29 Mar 2010 02:00 AM PDT A two-drug combination destroys precancerous colon polyps with no effect on normal tissue, opening a new potential avenue for chemoprevention of colon cancer, scientists report.

Searching for genes behind a trait Posted: 29 Mar 2010 02:00 AM PDT A new study located dozens of genes that may determine key traits such as flowering time and disease resistance in plants. The study of possible causal genes of plant traits breaks new ground for two reasons: the authors studied natural variation of 107 different traits -- a far higher number than in previous studies; and advances in genetic analysis enabled the authors to check the genome for mutations at many more points.

Topical drug to treat diabetic macular edema promising Posted: 29 Mar 2010 02:00 AM PDT Early-stage human clinical trials showed that a new topical drug was safe and had biological effects in a type of diabetic eye disease, and may offer researchers a new approach to prevent and treat diabetic macular edema.

Key enzyme discovered to be master regulator in protein-protein reactions Posted: 29 Mar 2010 02:00 AM PDT New research explains how a key enzyme, PP1, functions in protein-protein interactions. Researchers have described how PP1 "chooses" proteins. The finding is important, because erroneous PP1 regulation can cause numerous diseases, including cancer, diabetes and Parkinson's.

How does ethnicity affect asthma prevalence? Posted: 29 Mar 2010 02:00 AM PDT A study of UK schoolchildren has revealed that black Africans, Indians and Bangladeshis have a similar or lower prevalence of asthma than white children, while black Caribbean and mixed black Caribbean/white boys are more likely to have asthma. Researchers studied the occurrence of asthma, investigating ethnic differences in risk factors.

Commercial cooking elevates hazardous pollutants in the environment, study finds Posted: 28 Mar 2010 11:00 PM PDT Scientists in Minnesota are reporting that commercial cooking is a surprisingly large source of a range of air pollutants that could pose risks to human health and the environment.

How does a heart know when it's big enough? Posted: 28 Mar 2010 11:00 PM PDT A protein discovered in fruit fly eyes has brought scienetists closer to understanding how the human heart and other organs automatically "right size" themselves, a piece of information that may hold clues to controlling cancer.

Using nanotechnology in cancer research Posted: 28 Mar 2010 11:00 PM PDT Biomedical researchers in Norway are applying nanotechnology to mimic the body's natural processes, create new blood vessels to supply engineered tissue, and deepen our understanding of cancer.

Breast cancer and drug interactions: Making sure patients get full benefit of tamoxifen treatments Posted: 28 Mar 2010 11:00 PM PDT Some breast cancer patients taking tamoxifen may not be getting the full benefit of their treatment because they have also been taking selective serotonin reuptake inhibitors, prescribed drugs that inhibit the effect of an important enzyme, CYP2D6. In a new study, scientists have shown that by taking action as soon as interacting medications are found, patients can be weaned off and switched to a different treatment with no deleterious effect on tamoxifen metabolism.

Pressure sensors on alert Posted: 28 Mar 2010 11:00 PM PDT Vacuum panels are particularly good for insulating buildings -- as long as the vacuum does not leak. A tiny pressure sensor can now constantly check the condition of the vacuum and indicate whether the insulation effect is still present.

Patients requesting prophylactic mastectomies overestimate their breast cancer risk, study suggests Posted: 28 Mar 2010 11:00 PM PDT Women who have been diagnosed with breast cancer believe the risk of the disease occurring in their unaffected breast is as much as 10 times higher than it actually is. As a result, they are choosing to have prophylactic mastectomies based on a false perception of increased risk, according to new research.

A new strategy normalizes blood sugars in diabetes Posted: 27 Mar 2010 09:00 PM PDT Researchers have identified a new strategy for treating type 2 diabetes, identifying a cellular pathway that fails when people become obese.

Self-powered nanosensors: Nanogenerators used to power sensors based on zinc oxide nanowires Posted: 27 Mar 2010 09:00 PM PDT By combining a new generation of piezoelectric nanogenerators with two types of nanowire sensors, researchers have created what are believed to be the first self-powered nanometer-scale sensing devices that draw power from the conversion of mechanical energy.
